Occurrence Remarks: Small occurrence occupying only about 50 sq. meters consisting of about 150 to 200 plants growing directly in the shallow section of the pond near the edge. First observed here in 2015. Culms of plants all still green consistently for about 8 to 10 cm above the ice/ground level. C. aquatilus is found in valley locations along the Wasatch Front and in Utah contrary to indications in local floras; whether this occurrence represents an introduction is unknown: SL Co. Parks & Rec has no record of it being introduced here. The pond is manmade, but there are nearby natural marshes and springs in the area, and it is in the corridor of an abandoned channel of Big Cottonwood Creek.
